Back to original languageAbout Julien
Hello!
I am a full stack software engineer with 15 years of experience on numerous web projects.
I work on both backend (Ruby, Scala, Node.js), web frontends and hybrid mobile applications (React, Angular, Ionic), and infrastructure (AWS, Ansible, Docker, Kubernetes).
I bring my expertise to companies looking for a versatile and experienced person to:
- implement robust and scalable backends and APIs, in monolithic or microservices;
- develop or evolve hybrid mobile applications or web frontends;
- advise them in their technical and architectural choices: languages, open-source platforms, frameworks, system architecture, cloud infrastructure, etc.;
- create their prototype or MVP: architecture, implementation and production deployment;
- set up or improve their infrastructure and CI/CD pipeline, on dedicated servers or AWS;
- help them recruit their technical team;
Since 2009, I have worked with both medium-sized companies and startups, and I perfectly understand the challenges and concerns of each profile.
Furthermore, I have a background in Machine Learning that can be useful for adding intelligence to your solutions.
I have been working exclusively remotely since 2014.
Do not hesitate to contact me to present your project and understand how I can help you!
